Life is a spiritual battle between good and evil. Even for an individual. God (good) offers us love, peace, joy and fulfillment. Satan (evil) gives us the spirit of fear. He wants for us to be miserable and to blame God.
God gives us the freedom to make our own choices. He wants for us to choose Him (goodness) over evil (Satan). Satan gives us doubt. He uses our emotions to torture us and weaken us. God gives us armor to overcome evil. God is for us. He gives us life and freedom. All we have to do is call on Him, believe in Him, love Him and to be thankful. Satan wants to kill, steal and destroy us and our lives.
God gives us gifts of the Holy Spirit and gifts to do good. Satan wants to mislead us so that we will not use our gifts to do good. Negatives and negative thinking are tools that Satan can use against us. When we are ready to use our gifts to do good we have to get rid of the negatives and the old mindset. We have to put on the mind of Christ, trust in God and go for it. Resist the devil and he shall flee.
